If the DS2 switch is in ON position every switching on of the effect causes setting in the
DUAL REVERB the B parameters and switching it off causes setting back the
A parameters. In case of MIDI control each of the effects is considered as an individual
MIDI device (on different channels) and can be fully switched ON/OFF by controller or
other MIDI device.
MIDI channel setting
To set a MIDI channel on which the SD-1 receives the commands serves MIDI
CHANNEL rotatable switch. To change the channel use a small screw and turn it a little
right or left. The arrow-head indicates set channel (A, B, C, D, E, F letters correspond
with 10, 11, 12, 13, 14, 15 channels numbers and “0” digit indicates channel No. 16).
For CTRL OUT output the channel on which are received the commands is higher by
one than this set by MIDI CHANNEL switch (for channel No. 16 it is channel No. 1).
Controlling via MIDI commands
SD-1 can be controlled by Program Change and/or Control Change commands.
The table below shows functionality of the Program Change commands.
